| 摘 要： | 为验证苍山县沟西地区航磁局部异常，运用地面高精度磁测、勘查线剖面高精度磁测和钻探验证等综合勘查方法进行评价，依据Δ犜磁异常、高磁剖面异常和Δ犜化极向上延拓100 m 磁异常特征，首先预测了隐伏铁矿体的空间位置、产状，进而实施钻探验证，发现了苍山县沟西大型隐伏铁矿床，取得了良好的找矿效果，经对比分析已知矿体和磁场特征，建立了地质-物探找矿模式。

| Abstract: | In order to verify the regional aeromagnetic anomalies in Gouxi area of Cangshan county,by using complex exploration method,such as ground precision magnetic survey,precision magnetic survey of pros-pecting line profile and drilling verification,comprehensive evaluation has been carried out.Based onΔTmagnetic anomaly,high magnetic anomalies and magnetic anomalies by upwardΔTprofile 100m,spatial location and occurrence of hidden ore bodies have been predicated firstly,then carried out drilling verifica-tion,found Gouxi large scale hidden iron deposit in Cangshan county,and achieved good ore prospecting effect.After comparing and analyzing the known ore bodies and magnetic characteristics,geological-geo-physical prospecting model has been set up. |
